Support for non-time series data

[mihow]

There is an interest in using Antenna for batch ID of multi-subject images, which are NOT from a monitoring station or a sequential time series (museum drawers, images from dissection scopes, field collected specimens (bugbox), stiched DSLR photos, etc). Antenna works for this now (upload a folder of images, run the detection & classification pipeline). However you have to ignore several features that try to force the images into sessions and assume a time series. It would be interesting to make those features optional.
